Furthermore, the waterproofness / dustproofness of the joint between the tactile sensation providing apparatus 1 and the housing 5 can be further improved.

Abstract

L'invention se rapporte à un dispositif de présentation tactile, qui comporte : un panneau ; une partie de présentation tactile qui est située dans le panneau et qui le fait vibrer ; et une structure d'assemblage pour un boîtier. La structure d'assemblage est différente dans une première zone comprenant la partie de présentation tactile et dans une seconde zone distincte de la première.
